Added a database profiler function that can display database query execution times etc in the footer. Used for debugging.
Turn off debugging in attemptAction() in ShellController.php. Also added an extra line of debugging output too.
Code lines smaller than 2 characters long (but at least 1 character long) now appear in the rendered image.
Increased the `permissions_group` field’s max size (because some group names could be large).
